Dear Lijuan,
Please try to explain better your problem. What does it happen when you run
that command within Matlab? Do you get an error message? Nothing happens? ...?
I don't think the problem is mpi, the code should work anyway on one processor.
It works on my Ubuntu desktop with QE 5.0.3 a
Dear Filipe,
Thanks. I do have mpi installed. But I still cannot use Matlab to call pw.x
directly. Instead I use Matlab to submit the job file. It works now. But
the thing is that I need to make Matlab wait till the job finish.

Do you have mpi installed in machine?
type it in terminal:
locate mpirun
it should give you something like:
/usr/local/openmpi/bin/mpirun
/usr/local/openmpi/share/man/man1/mpirun.1
Regardless your linux provides a mpirun by default, I suggest you to
install it by yourself:

Dear everyone,
I am trying to use Matlab to call pw.x but it does not work. My command
line is
system('~/espresso/bin/pw.x< ~/debug/H2+H.in >H2+H.out'). I know it
probably because I need to first run mpi then call pw.x. But I cannot find
the mpi. Anyone knows how to do this. Thanks very much.
